Make and model?

Define "not constant"?

I have a similar problem with my 3 month old Worcester Bosch Heatslave 20/25
I get about 2 Minutes of lovely hot water then it goes cold I then have to
turn the hot water off for about 30 seconds and then I have hot water again.

In my experience, that's coming from the hw flow that you are actually
using being too low to trigger the burner. In my case, the less hot
water I want to draw the more likely it is that the burner goes off. I
need to open my tap at least halfway to get constant hw. It sucks
because it forces you to change your habits because of the combi (e.g.
doing the dishes under a constant, but small flow of hw - I know it's
not energy efficient, but I thought that I could decide how to do my
dishes, yet it's the combi that has taken over).

The 30s delay, in my case, allows the built in 3l tank to refill and
heat up again, mine is a WB 40 Greenstar Plus.

It seems different combis handle this situation in different ways. I did
an experiment with my Ideal Isar the other day, doing just what you
described i.e. running a very slow trickel of water. In fact I was
actully quite impressed with how well in handled it. On turning on the
tap the boiler fired up, but then shut down after 20 secs or so. It then
used its (small) internal store to supply water for a couple of mins
before ligting the burner again for approx 15 to 20 secs. All though
this it maintained a very constant output temperature. I seemed as if it
could carry on supplying water like this on an ongiong basis if required.
